100x Faster Broadband
An Australian researcher, who discovered a way to make ADSL broadband connections up to 100 times faster, has been offered a job in Silicon Valley in the US to continue his research.
Dr John Papandriopoulos, the 29-year-old research fellow of University of Melbourne, has developed an algorithm to reduce the electromagnetic interference that slows down ADSL connections.
The Channel Register has posted Dr Papandriopoulos’s explanation of his research:
“We formulate a (standard) model for how DSLs attain their data-rate, considering crosstalk interference effects.
We exploit the fact that interference varies across the frequency spectrum, and that if we are clever about the way in which we allocate transmission power amongst the various frequency bands, we can manage the interference between (strongly) coupled lines.
For example, one user that interferes strongly with others within a band may be “turned off” within that band to avoid damaging the other lines, consequently raising the overall network rate.”
Dr Papandriopoulos will be joining a Silicon Valley start-up company, ASSIA, which is developing ways to optimize the performance of DSL networks. Together with him is Stanford Professor John Cioffi, who developed the computer chips inside the first DSL modem.
According to SMH, Dr Papandriopoulos is in the process of assigning the intellectual property for his invention to the university, but he stands to receive significant royalties from any licensing agreements.
If this technology is successfully commercialized, the DSL broadband speed ceiling will be closer to 100Mbps. Dr Papandriopoulos expects that with licensed vendors, the technology could be implemented by internet providers around the world within two or three years, but he says the algorithms are very easy to implement in current ADSL modems.
